I just switched the second Hauppauge to two TechnoTrend budget DVB-C cards
(ie. now I have one Hauppauge + two TechnoTrends), and the problem seems to
have gone away.  When a CA channel recording is started and I'm watching some
FTA channel, I lose picture and sound for a couple of seconds, but that's not
a significant problem.  I have recorded different CA channels several times
now, and I've always been able to watch FTA channels normally.
